Genome editing of human embryos using CRISPR/Cas9- crossing the ethics of gene editing?

CRISPR/Cas9 system is a recently developed multi-purpose technology for genome editing [1,2] and its tool CRISPR-ERA/Cas9 is widely used as explained in the previous article [3]. The possible applications of this system have been discussed by its developers [4] and have been successfully applied for genome editing, gene function identification, and for gene therapy in animals and human cells [5-9]. Recently, a group of Chinese researchers has reported the editing of a genome using CRISPR/Cas9 system in human embryo for the first time in history [5]. The team has attempted to remove ‘harmful’ genetic codes to be potentially replaced by the ‘good’ ones. The results are published in Protein & Cell journal [10] but have opened a topic for debate over crossing the ethics of gene editing.
